Somewhere along the way, I fell in love with WinUI 3

FluentCleaner is a modern Windows cleanup tool built with WinUI3 and powered by the winapp2.ini ecosystem
Changelog
- [Added] ARM64 support for Surface, Snapdragon, and Copilot+ PCs. Full native stack (.NET 10, WinUI 3, Windows App SDK, CommunityToolkit, PowerShell) no emulation
- [New] Support for Winappx.ini; a new database format dedicated to AppX bloatware packages, separate from the existing Winapp2.ini cleaner entries. Something CCleaner never had. This is a terminal-only feature with four commands:
appx scandetects pre-defined bloatware,appx listdumps every installed AppX package on the system,appx remove <name>uninstalls any package by name, andappx remove allclears everything flagged by the scanner in one shot. Winappx.ini is a bundled database of 50+ bloatware entries across Microsoft, Office, Gaming, Social, and Media categories. Fully self-contained and no dependency on the existing cleaner infrastructure, runs entirely through PowerShell under the hood - [Changed] Executable renamed from Fluentr.exe to FCleaner.exe. The F stands for Fluent, not anything else your mind might jump to first
- [Added] Terminal now detects all enabled data Sources (winapp2, winapp3, custom etc), so commands work seamlessly across them and suggestions/autocomplete behave correctly
- [Added] Live scan Progress to see exactly which folder is being scanned in real time
- [Fixed] Entries that scan the entire system drive were silently scanning the wrong location (e.g. when searching system-wide files like
FileKey1=%SystemDrive%|*tmp|RECURSE) - [Fixed] Locked files like browser cookies were not showing up in scan results at all
- [Fixed] Selecting all entries during a search could silently wipe out selections outside the search results
- [Changed] App icon in titlebar and Settings refreshed
- [Changed] Terminal backend refactored into self-contained CLI modules with cleaner separation, easier to extend

Not required for the cleaner and completely independent.
Run FCleaner.exe to get started.
❤️ FluentCleaner is donation-supported.
Im building FluentCleaner as a donation-supported project. Learning WinUI 3 and turning this into a real app was definitely not painless, but it has been a lot of fun too.
If you like the project and want to support future releases, donations really help keep it going
